Question about Sony STR-DE345 Receiver
I have a Sony STR-DE345 5.1 channel and about two nights ago my basement door blew open, it was about 15 degrees out. Around two o'clock in the morning I heard a really loud buzzing noise coming from the basement it was the surround system. I can't even turn the volume to 1 the buzzing is so loud. If anyone has any answers they will be greatly appreciated.
Check all your wires and make sure that none of the wires that are powering any equipment (including extension cords, power bars, and power cables on the unit itself) are running parallel to any of the audio cables going to your speakers or from your inputs to your unit. This could be what's called AC hum, which is caused when the electrical current causes interference that gets picked up by the audio cables and amplified by your system. Just make sure you move the power cords as far away as possible from the audio cables.

If you don't want to buy new speakers, settle for safer low volume levels.
You're going to kill that receiver driving a 3-ohm load. HTS-style speakers aren't reliably re-deployable to other electronics. Perhaps, if you have 4 speakers and they're similar you could wire them in SERIES and present a 6-ohm load to each channel.
Re-engineering the speakers themselves is, well, don't do it. It isn't rocket science but it also isn
